PQC: Lattice-based signatures

In a recent discussion on the Bitcoin Development Mailing List, Mike shared valuable insights regarding the floating-point arithmetic in Falcon. He suggested that while the use of integer simulation to solve these arithmetic issues makes the algorithms less efficient compared to their native implementations, they still perform better than the SLH-DSA algorithm. This insight points towards a trade-off between efficiency and implementation complexity when dealing with cryptographic algorithms in blockchain development. It sheds light on ongoing efforts to optimize cryptographic techniques like Falcon within the constraints of computational practicality.
